Exposure Factors Influence Stone Deterioration by Crystallization of Soluble Salts

Abstract EN

The present work tries to determine the factors that influence the crystallization of soluble salts in the stone material used in the construction of buildings in Valencia (Spain).

Samples are obtained from a building which has served to accomplish observations and laboratory experiments necessary in order to determine the pathology of deterioration of the material.

It was particularized in the exposition conditions of the material as a base for determining the morphologies of deterioration caused by salts in the same lithotype.

The main contribution is the petrological study from the architectural point of view considering its orientation, sunlight in façade, and so forth.

This study proves that both material petrology (its mineralogy and texture) and the properties related to the movement of water inside rocks play a decisive role in the conservation and development of elements in the alteration.
